FRANK GREENLAND, OF BROOKLYN, NEV YORK.

SPECIFICATION forming part of Letters Patent No. 333,943 dated January 5, 1886.

Application filed July 22, 1885. Serial No. 172,294.

To all whom t may concern:

Be it known that I, FRANK GREENLAND, of Brooklyn, Kings county, in the State of New York, have invented a certain newand useful Improvement in Machines for Stapling Matting-Strands, of which the following is a speci iication.

I have in my experiments used the machine to insert staples for securing together the strands of cocoa matting, employing means for holding the strands in a wavy condition, leaving openings of approximately diamond shape, uniting the strands strongly at each junction by a staple, which is by my machine forced through two strands and clinched.

I will describe the invention as so used; but the novel features of the invention will serve in other relations.

The tool or machine is equipped with means for conveniently holding the strands in the required condition while each staple is inserted.

The accompanying drawings form a part of this specification, and represent what I consider the best means of carrying out the invention.

Figure 1 is a plan view, certain portions being in horizontal section. Fig. 2 is a corresponding elevation, partly in vertical section. The strong lines show both levers in the position assumed in thrusting a staple home. The dotted lines show one of the levers in the con'- dition required to allow a shifting from one junction to another. The drawn-forward position of the other lever is still more inclined than that of the one shown. Fig. 3 is a longitudinal central vertical section showing a staple thrust home. Fig. 3n is a cross'section of one of the details detached. Fig. 4 is a View of a portion of the opposite side from that shown in Fig. 2.

Similar letters of reference indicate corresponding parts in all the figures where they occur.

The work is performed on a plane bench, A, in which are inserted stout abutment-pins B, hollowed on their front faces, as indicated by b, and other pins, B B2, which serve to hold the strands in the correct position. The front of the machine abuts against a block, A, of the bench A, and the position of the machine may be changed from one point to another (No model.)

along said block, to bring it into operation at different points. v

The strands of mat material are indicated bym. The staples are not shown. Their positions are indicated in dotted lines at N. The strand m is placed by hand in its approximatelycorrect position, and the tool is brought into action first to press together at the desired points the strands m m, which may in practice be parts of the same continuous strand. After the strands are firmly compressed together by the working of one lever, the working of ari-- other lever sets the staple. The turning of both levers forward, either simultaneously or successively, sets the tool free and allows it, being turned and sliding in the obvious manner, to be brought into position for the next junction, and so on.

D D is the base or body, in the back end of which are bored or otherwise produced two horizontal parallel holes, in which are received corresponding guides,El E2,cXtending forward from a cross-head, E, which latter carries a peculiarly formed post, E3. The staples N are deposited, by hand or otherwise, in the correspondinglyshaped recess, e, which extends uniformly up and down. post is a slide or door, E, which may be removed and replaced at will. The back face of the crosshead E is slightly rounded and adapted to hold the strand firmly against the corresponding part to which it is to be stapled. This part is operated by a hand-lever, F', which is keyed or otherwise firmly set on a shaft, F, which extends horizontally through the body D, and is equipped with two rigidlyconnected arms, F2 F2, one on each side of the body. These are connected by rivets G and links I-I to pins E5 E5, set one on each side of the cross-head E.

I is another lever turning on a shaft or transverse pin, I. It has a short arm, I2, standing at a small angle to the lever I. This connects by a knuckle-joint, t', the link J, and pin j to a carriage, K, which is capable `of moving forward and backward in a corresponding passage inthe body D. A rigid arm, K, of steel or other suitable material, extends backward from this carriage through a closeftting aperture inthe crosshead E. This aperture is directly below the recess e or pecu liar vertical double groove in E, which holds The front of this IOO the staples. The arm K is of sufficient width to act fairly against the staple to drive it.

In operating, the lever F' is drawn forward, which throws the device out of action, and the body D,with its attachments, may then be shifted to the position required to thrust the first staple. Then the lever Fis thrust backward, or from the operator, bringing the arms F2 Fz and the connected links H H into a horizontal position, as shown in strong lines in Fig. 2. This movement thrusts the crosshead E backward, compressing the strands m m with tolerable firmness betweenits rounded back and the concaved adjacent face b of the post B. The parts are now ready to set the staple. The lever I is next thrust sharply backward, and the arm K', striking the lowermost staple, separates it from its companions and thrusts it through the two strands m m. The concave form of the recess Z) insures that the points of the staple, on being thrust through, are curved smoothly inward or toward each other and clinched. N ow the operator draws forward both the levers F and l'. This, by the movement of the lever F' and its connections, relaxes the pressure of the cross-head E against the strands, and by the withdrawal of the carriage K and arm K entirely disconnects the cross-head from the finished joint just made, leaving the device free to be shifted to a new position and the operation repeated.

It will be observed that the pressure of the rounded face of the cross-head E adjusts the strands in the correct position. It follows that the diamond figures produced by the use of this tool or machine will be uniform. Allowance should be made, however, for the dispol. The combination,with the body D, lever l F', and carriage or cross-head E, operated by said lever and having a recess for receiving a number of staples, N, of the lever I', carriage K, and arm K', operating through the crosshead to drive the staples, all arranged for joint operation, as herein specified.

2. The crossvhcad E and means, as F H, for reciprocating it, in combination with the arm K', the carriage K, and means, as I' I2 J, for reciprocating it, arranged for joint operation relatively to each other and to strands m m of a mat and abutting pins B B B2, substantially as herein specified.

3. The bench or supporting means A, abutting pins B, with concavcs b, and additional pins, as B' B2, for holding the strands in position, in combination with each other and with the cross-head E and arm K', and means, substantially as described, for operating the arm and cross-head, as set forth.

In testimony whereof I have hereunto set my hand, at New York city, this 22d day of June, 1885, in the presence of two subscribing witnesses.

FRANK GREENLAND.
